its like any advice, no matter who one gets it from
one takes it with a grain of salt, and sometimes you
get what you paid for.
i can't tell you how much bad advice i have gotten from people
about everything from places to buy "stuff" photographic advice,
artisans ( cobblers, tailors ) restaurants &c ... even the most
respected people i know have given me bum advice ... its just advice, what can you do ...
people here on apug ( and everywhere else ) for example, have in years gone by given advice
in subjects they had absolutely no idea what they were talking about ... made completely false statements
about everything under the sun ( and sometimes people advise others to do things that are ILLEGAL ! )
whatever ... its just the internet ...
i've even gone to a store and was given bad advice from someone behind the counter. i just made sure
not to ask for advice after that .. and did my own research and figured it out.
